An undulating topography
Lausanne is situated at 46°32 latitude north and at 06°38 longitude east on the northern shore of Lake Geneva. It has a steeply sloping relief ranging from 370m by the lake to 870m in the deciduous and pine forest of Jorat. It rests on the molasse characteristic of the Swiss plateau and on moraines deposited by alpine glaciation.
A temperate climate
Rainfall is evenly distributed throughout the year. Average temperatures are between 3°C and 20°C, while extremes can touch -10°C and +37°C. The winds in the region are the “bise”, which blows from the north-east bringing cold air from high pressure systems in Siberia, the “foehn”, a warm wind from the alpine valleys, and the south-westerlies, which transport temperate, humid and sometimes stormy air masses from the Atlantic.
